织梦模板中使用js记录浏览历史并调用历史记录

天外飘仙

织梦的这两个函数很重要。织梦模板中使用js记录浏览历史并调用历史记录 他直接简化了JS的COOKIE。让他由复杂变的简单了。这两个函数在AJAX里面的。
在include/js/dedeajax2.js里面，

1. //读写cookie函数
   
2. function GetCookie(c_name)
   
3. {
   
4. if (document.cookie.length > 0)
   
5. {
   
6. c_start = document.cookie.indexOf(c_name + “=”)
   
7. if (c_start != -1)
   
8. {
   
9. c_start = c_start + c_name.length + 1;
   
10. c_end = document.cookie.indexOf(“;”,c_start);
    
11. if (c_end == -1)
    
12. {
    
13. c_end = document.cookie.length;
    
14. }
    
15. return (document.cookie.substring(c_start,c_end));
    
16. }
    
17. }
    
18. return null
    
19. }
    
20. function SetCookie(c_name,value,expiredays)
    
21. {
    
22. var exdate = new Date();
    
23. exdate.setDate(exdate.getDate() + expiredays);
    
24. document.cookie = c_name + “=” +escape(value) + ((expiredays == null) ? “” : “;expires=” + exdate.toGMTString()); //使设置的有效时间正确。增加toGMTString()
    
25. }
    
26. –>

增加一个函数。
如下：

1. function getCookies(ids,title,img){
   
2. var saveid = GetCookie(‘id’);
   
3. var savetitle = GetCookie(‘products’);
   
4. var saveimg = GetCookie(‘images’);
   
5. if(saveid != null && savetitle != null && saveimg != null)
   
6. {
   
7. var saveids = saveid.split(‘,’);
   
8. var savetitles = savetitle.split(‘,’);
   
9. var saveimgs = saveimg.split(‘,’);
   
10. var hasid = false;
    
11. saveid = ”;
    
12. savetitle = ”;
    
13. saveimg = ”;
    
14. j = 1;
    
15. for(i=saveids.length-1;i>=0;i–)
    
16. {
    
17. if(saveids[i]==ids && hasid) continue;
    
18. else {
    
19. if(saveids[i]==ids && !hasid) hasid = true;
    
20. saveid += (saveid==” ? saveids[i] : ‘,’+saveids[i]);
    
21. savetitle += (savetitle==” ? savetitles[i] : ‘,’+savetitles[i]);
    
22. saveimg += (saveimg==” ? saveimgs[i] : ‘,’+saveimgs[i]);
    
23. j++;
    
24. if(j==10 && hasid) break;
    
25. if(j==9 && !hasid) break;
    
26. }
    
27. }
    
28. if(hasid) { return false; }
    
29. else saveid += ‘,’+ids;
    
30. savetitle += ‘,’+title;
    
31. saveimg += ‘,’+img;
    
32. SetCookie(‘id’,saveid,1);
    
33. SetCookie(‘products’,savetitle,1);
    
34. SetCookie(‘images’,saveimg,1);
    
35. }
    
36. else
    
37. {
    
38. SetCookie(‘id’,ids,1);　　　//这个是ID。用来做链接用的
    
39. SetCookie(‘products’,title,1);　//这个是标题，用来显示在页面的
    
40. SetCookie(‘images’,img,1);　//这个是图片
    
41. }
    
42. }

2.在页面引用js.

1. <script language=”javascript” type=”text/javascript” src=”{dede:global.cfg_cmsurl/}/include/js/dedeajax2.js”></script>
   
2. <script language=”javascript” type=”text/javascript”>
   
3. getCookies({dede:field.id/},’{dede:field.title/}’,’{dede:field.litpic/}’)
   
4. function CheckLogin2(){
   
5. var taget_obj = document.getElementByIdx_x_x(‘_userlogin’);
   
6. myajax = new DedeAjax(taget_obj,false,false,”,”,”);
   
7. myajax.SendGet2(“{dede:global.cfg_cmspath/}/member/ajax_loginsta2.php”);
   
8. DedeXHTTP = null;
   
9. }
   
10. </script>

调用历史记录的代码：

1. <div class=”Recommend h-394″>
   
2. <h1 class=”rec-bg”><span class=”span-rt-3″><a onclick=”destroy_cookie()”>清空</a></span>最近浏览过的课程</h1>
   
3. <ul class=”w-223 browse ” id=”viewHistory”>
   
4. <script type=”text/javascript”>
   
5. function destroy_cookie(){
   
6. SetCookie(‘id’,”,1);
   
7. SetCookie(‘products’,”,1);
   
8. SetCookie(‘images’,”,1);
   
9. document.getElementByIdx_x_x(‘viewHistory’).innerHTML=””;
   
10. window.alert(‘你已成功清除浏览历史记录！’);
    
11. }
    
12. </script>
    
13. <script type=”text/javascript”>
    
14. var saveid = GetCookie(‘id’);
    
15. var savetitle = GetCookie(‘products’);
    
16. var saveimg = GetCookie(‘images’);
    
17. if(saveid != null && savetitle != null)
    
18. {
    
19. var saveids = saveid.split(‘,’);
    
20. var savetitles = savetitle.split(‘,’);
    
21. var saveimgs = saveimg.split(‘,’);
    
22. var hasid = false;
    
23. saveid = ”;
    
24. savetitle = ”;
    
25. saveimg = ”;
    
26. for(i=saveids.length-1;i>=0;i–)
    
27. {
    
28. document.write(“<li>” +”<div class=’w-53′><a href=\”/plus/view.php?aid=”+saveids[i]+”\” title=\””+savetitles[i]+”\”><img src=’”+saveimgs[i]+”‘ width=’52′ height=’51′/></a></div><p class=’w-53-rt’><a href=\”/plus/view.php?aid=”+saveids[i]+”\” title=\””+savetitles[i]+”\”>”+savetitles[i]+”</a></p></li>”);
    
29. }
    
30. }
    
31. </script>
    
32. </ul>
    
33. </div>
